'Expand All' for Adjust Items

It would be really nice to be able to select multiple adjust items and 'Expand All' to get to the underlying 'real parameters'; or otherwise have some way to select them without having to expand the items. I often want to make all the parameters have the same range and step size. In order to select all the 'real parameters', it appears that I have to click on all the plus signs individually to get there. Ideally, it would be nice to use a shift-click to get all the parameters, but when selecting them this way, the items are selected as well.
